What is the CORI Surgical System?
The CORI Surgical System is an advanced robotic platform designed for orthopedic surgeries, particularly knee replacement procedures. Developed by Smith & Nephew, this handheld robotic system leverages robotics and computer-assisted technology to enhance precision and efficiency during surgical procedures.
What are the Key Features of the CORI Surgical System?
Some of the key features of the CORI Surgical System include:
- Robotic Assistance: The system aids surgeons in planning and executing precise bone cuts and implant placements, aiming for better alignment and fit of the prosthetic components.
- Real-Time Data: The system provides real-time feedback and data to the surgeon, helping to make informed decisions during the procedure.
- Customization: It allows for personalized surgical plans tailored to the individual patient's anatomy, potentially improving the overall outcome of the surgery.
- Enhanced Visualization: Surgeons benefit from enhanced visualization of the surgical field, improving accuracy and control during the procedure.
- Training and Support: Smith & Nephew provides comprehensive training and support for surgeons using the CORI Surgical System, ensuring they can effectively utilize the technology in their practice.
Indications for CORI Surgical System
Smith & Nephew’s CORI surgical system is typically indicated for partial and total knee replacement in patients suffering from degenerative knee disease, such as osteoarthritis, that is not responsive to conservative treatment.
Osteoarthritis is a degenerative joint disease that causes breakdown and eventual loss of cartilage in the knee joint making the bones rub against each other leading to painful movement.
Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn-out or damaged surfaces of the knee joint are removed and replaced with an artificial knee implant or prosthesis. Partial knee replacement is a surgical procedure in which only the damaged portion of the knee joint is removed and replaced with a prosthesis.
Preparation for Knee Replacement Using CORI Surgical System
In general, preparation for knee replacement using the CORI Surgical System may include the following:
- A review of the patient's medical history, including any previous surgeries, medications, and overall health status, as well as a physical examination of the knee and surrounding structures will be conducted.
- Routine blood tests, EKG, and other preoperative tests are performed to ensure the patient is fit for surgery.
- Imaging studies, such as X-rays, MRIs, or CT scans of the knee are taken to assess the extent of joint damage and to plan the surgery. These images help in creating a detailed map of the knee's anatomy.
- Using the imaging data, a personalized surgical plan is created. The CORI Surgical System uses this data to assist in planning the precise cuts and implant placements.
- The patient may be asked to stop certain medications, such as blood thinners that pose a risk of bleeding during surgery, as well as provide detailed instructions on fasting before surgery.
Procedure for Knee Replacement Using CORI Surgical System
In general, knee replacement using the CORI Surgical System may include the following steps:
- Setup: The patient is positioned on the operating table, and the surgical area is sterilized. Anesthesia (general or regional) is administered.
- Registration: The CORI Surgical System's handheld device is used to map the anatomy of the knee joint. This registration process involves capturing precise data points on the bone surfaces.
- Robotic Assistance: Based on the preoperative plan and real-time data, the CORI system assists the surgeon in making precise bone cuts. The handheld device provides tactile feedback and guidance to ensure accuracy.
- Bone Preparation: The damaged portions of the femur (thighbone) and tibia (shinbone) are removed using the robotic system. The surface is then prepared to fit the prosthetic components.
- Implant Positioning: The prosthetic components are placed and secured in the prepared bone surfaces. The CORI system ensures that the implants are positioned accurately according to the preoperative plan.
- Balancing the Knee: The surgeon checks the alignment and balance of the knee joint to ensure proper function and stability. Any necessary adjustments are made.
- Closure: The surgical incision is closed using sutures or staples, and a sterile dressing is applied.
Postoperative Care and Recovery
Following surgery, you will require pain management with medications and ice packs. Incision site care and bathing instructions will be provided to keep the wound clean and dry. You should refrain from strenuous and heavy lifting activities for a defined period. A knee brace or immobilizer may be recommended to protect the repair, depending on your surgeon’s preference.
The healing process may take anywhere from 8 to 12 weeks. You will require the use of crutches until you are able to walk without assistance. A physical therapist will teach you specific exercises to strengthen your leg muscles and restore knee movement. You should be able to resume your normal activities in a couple of months. Follow-up appointments will be scheduled to monitor your progress.
Risks and Complications
Knee replacement using the CORI Surgical System is a relatively safe procedure; however, as with any surgery, some risks and complications can occur, such as:
- Pain
- Bleeding
- Infection
- Knee stiffness/instability
- Blood clots or deep vein thrombosis (DVT)
- Allergic/anesthetic reactions
- Injury to nerves or blood vessels
Benefits
Benefits of knee replacement using the CORI Surgical System include:
- Smaller incisions
- Minimal postoperative pain
- Minimal muscle trauma/scarring
- Greater accuracy in implant placement
- Improved implant longevity
- Shorter hospital stay
- Rapid recovery
- Lower risk of revision replacement
- Higher patient satisfaction
